Openstack Rocky with manila installed, I try to modify a existing project quotas and Horizon throws a generic error while apache error log shows:

UnhashableKeyWarning: The key of openstack_dashboard.usage.quotas tenant_quota_usages is not hashable and cannot be memoized: ((<weakref at="" 0x7f2c89b5d6d8;="" to="" 'wsgirequest'="" at="" 0x7f2c89ba4490="">,), (('targets', ('share_snapshot_gigabytes', 'share_gigabytes', 'share_snapshots', 'shares', 'share_networks')), ('tenant_id', u'fda8882b264b48a2929949aa8ab27 176')))

Any ideas ?
